Field Theory And The Cohomology Of Some Galois Groups

open access: yes, 2007
. We prove that two arithmetically significant extensions of a field F coincide if and only if the Witt ring WF is a group ring Z=n[G]. Furthermore, working modulo squares with Galois groups which are 2-groups, we establish a theorem analogous to Hilbert&
